Availability: Available
4QD Item #: HRB-312 -

These HRB relay boards are designed to control 3 or 4 relays from one of the 4QD hand throttles. Often used for lights and horns on model locomotives they can be used in many other applications. The circuit allows control of either 3 or 4 relays with only 2 or 3 wires. It also has a number of ''break points'' on the circuit board that gives it a lot of flexibility to be used with [e.g. sound] systems that require isolated switch inputs.Miniature locomotives often need to operate twin horns and...

4QD JSB-002 Joystick Interface Board
Price: $34.99
View
Availability: Available
4QD Item #: JSB-002 -

A joystick (aka wig-wag control) is essentially a potentiometer with a lever attached. As you move the lever forward from the centre position the motor starts to rotate in one direction. Moving the lever backwards causes the motor to rotate in the opposite direction. This interface converts a single DNO, VTX or Pro-120 series controller to joystick input. The 6 way connector is for pin-to-pin connection with the Pro-120, DNO, or VTX. The 3 way connection is for the ignition switch and battery...

4QD Item #: BNL-103 -

The 'Naked Bell Assembly' is a finger-tip throttle assembly (speed control mechanism) using the 50 degree pot. It has a spring return to zero and is supplied with a mounting bracket and a vinyl-capped lever. The spring is light operation to minimize finger strain from continuous pressure on an over-strength spring, yet is still strong enough to ensure reliable operation. The lever can safely be bent if a different shape is needed. This feature means that if the lever gets accidentally bent, it...
